    From Joaquin,
                I'll get this in on Monday my time if no one else beats me to
    it.

    I haven't looked at the code yet but knowing Joaquin I'm sure it works
    exactly as he says it does.

    This widget copies the MS Word/ WordPerfect insert table control which
    allows you to insert a table of the size want by dragging the mouse across
    a little table.

    Cheers

    Martin

    Subject: insert table widget

    Martin, sorry for not giving you any news for so long.

    Here you have the promised "insert table widget". I've called it
    AbiTable.

    It still has some problems:

    * It don't ears GtkToolbar style changes.
    * If you just click on the icon, the table window appears and disappears
    instantly, instead of sticking (like in Word).
    * I did the icon before looking at the recent Dom mail, so you can just
    change my icon by Jimmac one :)
    * It needs some little cosmetics changes here and there.

    But except for that, it works well imo. And I'm pretty sure I can fix
    these two problems without changing the API, so it should not be a
    problem if we integrate it with abiword right now and fix these latter.

    I've provided you a complete example to use it. It's in main.c (mainly
    borrowed from demo-gtk :).

    In short, to put it in a toolbar you should:

    GtkWidget* abi_table = abi_table_new ();
    g_signal_connect_object (abi_table, "selected",
                             G_CALLBACK (new_table_cb), NULL, 0);
    abi_table_embed_on_toolbar(ABI_TABLE(abi_table), GTK_TOOLBAR(toolbar));

    It's not strickly necessary to use abi_table_embed_on_toolbar to put the
    widget in the toolbar. AbiTable inherits from GtkButton, and thus you
    can just insert it in the toolbar with gtk_toolbar_insert_widget, but
    that way the AbiTable widget will hide or show the label or/and the icon
    in function of the toolbar style. And to fix the first problem I should
    just add a bit of code to this function, so if you just use
    embed_on_toolbar, it will be easier in the future to integrate a new
    version.

    new_table_cb should be a function with the signature:

    static void new_table (GtkWidget *table, int rows, int cols, gpointer*
    data);

    where table is our AbiTable, rows and cols are the selected rows and
    cols by the user, and data is the typical user_data of connect_object.

    This signal will fire when the user creates a new table with the widget.

    I've enclosed the interesting code in main.c between <MARTIN> ...
    </MARTIN> tags.

    Attached you have a little screenshot of the widget.

    Cheers,

    P.S.: I know that it kind of sucks to ask you to do "my" work, but I'm
    sure that this way it will be done much faster :)
